I need to find some replacement transistors for my Orion Cobalt CO430
amp.

The amp has a row of six heatsinked transistors along each side of the
circuit board. The part I need is labelled:

ORION
0490-0210
T9418AJ

The OTHER transistors along the same row (but which look visually OK
in my amp) are labelled:

SMW20P10
T9418AB
TAIWAN

There is also a triangle symbol that precedes the T9418__ part numbers
on each part.

The new parent company of Orion wasn't able to help. They told me
they didn't keep any parts lists from products made by the old
company. I tried Digi-Key and a couple other parts suppliers, but
they didn't have a cross-reference.

Can anyone provide a replacement part number? My car got flooded and
these parts burned up in the amp under my seat. I'd rather replace
the parts than buy a whole new amp, since it looks like an easy job to
replace them (along with a 10-ohm resistor that also fried).

Thanks to anyone who can help.

I typed t9418AJ in the obsolete components section of this web site and
they list they have this part. www.ajjeas.com

If your amp got flooded you've got more than just a few fried transistors.
You might want to start amp shopping.

I figured that would be a MOSFET p/n, but just for the hell of it did a
simple search at Yahoo, found this:

QUESTION NO. P814-5: Orion Cobalt 260 car audio amp. I need a source
for part numbers smw20p10 and smw45n10. I believe these are old
Siliconix part numbers, but I am not certain. Direct or upgrade
replacement parts would be fine. SMW20P10 (P-channel) and SMW45N10
(N-channel) are 100 Volt Mosfets, in TO-247AD cases. You might
substitute IRF's IRFP9140 for SMW20P10, and IRFP150N or ST Micro's
STW50N10, for SMW45N10. Digikey (www.digikey.com) carries the IRF
lineup, and Mouser (www.mouser.com) carries ST Micro FET's. These
substitutes use the TO-247AC style case, which has slightly shorter
leads than TO-247AD, if that matters.

Amazing what a search engine is good for...

Thanks, John! I'll give those a try and hope for the best, it won't
cost much to try.
